Getting to Khao Yai

Most visitors drive from Bangkok to the Pak Chong area in roughly 2.5–3.5 hours, depending on traffic, following Highway 1 and Highway 2 then Thanarat Road (Route 2090) to the park’s northern gate. Sections of the new M6 motorway have been opening in stages — check the latest status before you set off. State Railway of Thailand trains run from Krung Thep Aphiwat Central Terminal to Pak Chong (book via SRT D-Ticket). There is no public transport inside the park.
